I get the following:

use warnings;
use strict;
use Data::Dumper;

chomp( my @array = <DATA> );

for (@array) {
    chomp;
    if (/^lib$/) {
        print "Yes: $_\n";
    }
    else {
        print "No : $_\n";
    }
}

print "\n", Dumper \@array;

__DATA__
nfcclib
lib
[download]

Output:

No : nfcclib
Yes: lib

$VAR1 = [
          'nfcclib',
          'lib'
        ];
[download]

Consider using Data::Dumper to examine the array's elements.

Hope this helps

Edit: Added Data::Dumper.
